2'0 all! whom, it may concern.-

Be it known that I, GEORGE A. HOLM, a citizen of the United States,residing at Mansfield, in the county of Richland, State of Ohio,

' haveinvented certain new and useful Improvements inPerforating-Maehines, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention is a device for. perforating paper. It is adapted to beapplied or attached to any cylindrical printing-press.

Figure 1 is a transverse sectional view of my invention attached to thesides of a printing press. Fig. 2 is an elevation of the de vicedetached. Fig. 3 is a perspective view of the ends of two shafts and thehinged clamp rigidly uniting the same. Fig.4 representsa planfragmentary View of thecylinder and its circumferential band.

Like letters indicate like parts throughout the several Views.

A indicates a shaft having its ends soon red to the inner sides of thepress-frame.

B is a shaft lying parallel to the shaft A and secured thereto by meansof the clamps G (J. The clamps G are provided with two collars, O G".The collar '0 is provided with a hinged portion, WVhen the hingedportion 0 of the collar is closed it is secured to the clamp neck orshank by a'bolt, D, said bolt passing through the hinged portion andclamp-neck, substantially as shown in Fig. 3. The collar 0 is providedwith athreaded bossopening for the reception of the threaded end of thebolt E. The bolt E enters said opening, and when screwed in rigidlyunites the shaft B with the collar 0. The collar 0 its hinged portion 0,and the bolt D serve to rigidly unite the shaft A and said collar.

F F represent two sleeves secured to the shaft B at any desired pointsby the set-screws F. The set-screw passes through a threaded opening inthe sleeve.

G represents an arm rigidly, fixed to the sleeve F. This arm is providedwith an opening on its upper end for the reception of the threaded boltH.

H is a threaded thumb-nut on the outer end of the bolt H.

I is a lug rigidly fixed to the sleeve F.

J is a bifurcated arm, having a perforatingwheel, K, journaled therein.The periphery of this wheel is serrated,so as to perforate the paperwhen it is passed between said wheel and the press-cylinder. Theonterend of the bifurcated arm J isjointed at J to the lug I.

L represents a spiral spring encircling the inner end of the threadedbolt H between the arms G and J. r

The object of the jointed lug and arm I J, bolt H, thumb-nut H, andspiral spring L is to regulate and adjust the pressure of theperforating-wheel K against the paper 011 the press-cylinder M--that isto say, the spiral spring L may be longitudinally expanded or contractedby operating the thumb-nut H and the pressure of the perforating-wheel Kon the paper thereby increased or diminished at pleasure. The inner endof the bolt H is pivoted at h to the jointed arm J. The periphery of thecylinder on the line of travel of the wheel K is provided with acircumferential band, M, of wood, lead, or other suitable material, toprevent the wheel from cutting into the cylinder while in operation. Themain shaft A having its i11- ner ends fixed to the sides of the press,serves to strengthen and brace the press. By adj ustably attaching theparallel shaft B to the fixed shaft A said shaft B may be firmly held inVa rious positions. By means of the clamps O the shaft B and itsconnected mechanism may be laterally adjusted along the shaft A, or saidshaft B and its attached parts may be swung backward and downward, whendesired that is to say, moved in the arc of a circle around the shaftAwhcreby the perforatingwheels K may be adjusted in relation to theperiphery of the cylinder.

The matter for printing is attached to the revoluble cylinder by theclamping device now in use,0r any suitable means. Before the paperreaches the type the said paper, by

the movement of the cylinder, is passed between the rotaryperforating-whecl K and the periphery of the cylinder. The rotation ofthe cylinder rotates the perforating-wheel K, and thereby perforates thepaper which passes between said wheel and cylinder. is therebyperforated before it is brought in contact with the type.

The sleeve F and its connected devices carrying the perforating-wheel islongitudinally adjustable on the shaft 13, whereby said per- The paperIOO forating-wheel may be caused to travel on any circumferential lineon the periphery of the cylinder. Any suitable number of these devicesmay be placed upon the shaft K.

The shaft B may be rotated in clamps O to throw all of theperforating-wheels at once out Having thus described my invention, I

claim as new and desire to secure by Letters, Patent- 1. Thecombination, with the printing-press linder ofa erforatin -wheel ada)ted to bear y p D upon said cylinder, a movable bearing and support forthe wheel, and a spring pressing upon the outer side of said support orhearing, whereby the wheel may be held against the cylinder with ayielding pressure, substantially as set forth.

2. A perforating attachment for printingpresses, consisting in thecombination of a jointed arm-provided on its outer end with aperforating-wheel, a bolt threaded on its outer end and having its innerend pivoted to said arm, a relatively fixed arm provided with an openingfor the reception of said bolt, a spring interposed between said arms,and a threaded nut on the outer end of the bolt aforesaid, substantiallyas specified.

3. A. perforating attachment for printingpresses, consisting in thecombination of the fixed shaft A, parallel shaft B, and unitingclamps,the shaft B being rotatable and 1ongitudinally adjustable in the eyes 0of the clamp-bearings, and adapted to be clamped therein at the desiredpoint by setscrews F of the rotatable sleeve F, longitudinallyadjustable on the shaft B, said sleeve being provided with a lug havinga springactuated arm jointed thereto, the outer end of said arm beingprovided with a perforating-wheel, substantiall y as specified.

4. A perforating attachment for printingpresses,consisting in a fixedshaft lying parallel with the axis of the cylinder, a parallel shaft, B,and clamps for connecting the two shafts, each of said clamps beingprovided with two collars for the reception, respectively, of the twoshafts, one of the collars being provided with a hinged section andmeans, sub stantially as described, for locking the same, wherebytheshafts may be held in a fixed relative position or the shaft B detached,in combination withan adjustable sleeve on the shaft B, said sleevebeing provided with a lug having a spring-actuated arm jointed thereto,
